  1. 21. Network Modelling of Port Terminals Development of a Concept and a Tool

    Författare :Karl Jansen; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; combinatorial graph theory; optimisation; port terminals; complex node functionalities; modelling of information; implementation of a tool;

    Sammanfattning : Network theory can be used to model and optimise logistic systems. The movement of goods is a major issue in our society and there is a large potential for increased efficiency in the transportation systems. Terminals and their equivalents are important in logistic systems. This is especially obvious when it comes to sea transport. LÄS MER

  3. 22. Air - for Health and Comfort, An Analysis of HVAC Systems' Performance in Theory and Practice

    Författare :Fredrik Engdahl; Avdelningen för Byggnadsfysik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Byggnadsteknik; Building construction; indoor air quality; HVAC; infiltration; ventilation; VAV;

    Sammanfattning : One part of the objective is to analyze how different ventilation systems perform in practice when it comes to supplying and exhausting designed air flow in different outdoor and indoor conditions. The other part is to analyze the design criterias and the energy use of a variable air volume system based on controlled static pressure at the branch duct level and supplying outdoor air only.

  4. 23. Charge and Energy Noise from On-demand Electron Sources

    Författare :Nastaran Dashti; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Boltzmann-Langevin approach.; fluctua- tions and noise; single-electron source; energy and heat currents; time-dependently driven mesoscopic capaci- tor; charge current; Floquet scattering theory;

    Sammanfattning : On-demand single electron sources (SES) are of key importance for future electronic applications such as metrology or quantum optics with electron. They allow for achieving a controlled, low-fluctuations flow of particles in a coherent mesoscopic conductor. LÄS MER

  5. 24. Physics of blood flow in arteries and its relation to intra-luminal thrombus and atherosclerosis

    Författare :Jacopo Biasetti; T. Christian Gasser; Danny Bluestein; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Vascular pathologies such as Abdominal Aortic Aneurysm (AAA) and atherosclerosis are complex vascular diseases involving biological, mechanical, and fluid-dynamical factors. This thesis follows a multidisciplinary approach and presents an integrated fluid-chemical theory of ILT growth and analyzes the shear-induced migration of red blood cells (RBCs) in large arteries with respect to hypoxia and its possible role in atherosclerosis.

  7. 25. Synchronous Voltage Reversal Control of Thyristor Controlled Series Capacitor

    Författare :Lennart Ängquist; KTH; []
    Nyckelord :ThyristorControlled Series Capacitor; TCSC; FACTS; reactive power compensation; boost control; phasor estimation; Quantitative Feedback Theory; subsynchronous resonance; SSR;

    Sammanfattning : Series compensation of transmission lines is an effectiveand cheap method of improving the power transmission systemperformance. Series capacitors virtually reduces the length ofthe line making it easier to keep all parts of the power systemrunning in synchronism and to maintain a constant voltage levelthroughout the system.
